What are the best practices for using useReducer in React?

When using useReducer, it's important to keep your reducer pure, manage state updates efficiently, and avoid deeply nested state.

Can you explain what you mean by keeping the reducer pure?

A pure reducer means it should not have side effects and should return the same output for the same input, ensuring predictable state transitions.

How can I manage state updates efficiently?

You can manage state updates efficiently by batching actions and using memoization techniques to prevent unnecessary re-renders.

What should I do if my state becomes too complex?

If your state becomes too complex, consider splitting it into multiple reducers or using context to manage related state separately.
